In a unit circle, any line that starts at the center of the circle and ends at its perimeter will have a length of 1. So, the longest side of this triangle will have a length of 1. The longest side of ...

The unit circle is defined as a circle of radius 1, centred on the origin. The circumference around a circle is given by C = 2 π r. As the radius of the unit circle is 1, the circumference is C = 2 π ...
